A shaft is guided outward on both sides through the housing. The shaft transfers
the reaction torque to a process valve (è Fig.1,8). A limit switch or position
sensor (è Fig.1,1) can additionally be fitted. The flange to the process valve is
designed in accordance with ISO5211. The housing underside has a hole pattern
for valve mounting in accordance with VDI/VDE 3845 (NAMUR).

5.2 Function
In the DAPS, the movement of the piston is transformed using a Scotch yoke sys-
tem into a swivel motion of the transmission shaft. This kinematic system is only
effective within an angle of approx. 90°.
Double-acting semi-rotary drives
Fig. 2 Symbol – double-acting semi-rotary drive
Pressurising and exhausting the cylinder chambers causes the shaft to move back
and forth. The linear motion of the shaft is transformed into a swivel motion.
Single-acting semi-rotary drives
Fig. 3 Symbol – single-acting semi-rotary drive
Return is through spring force.
5.2.1 Manual override
The handwheel can be used to change the position of the drive with the supply
pressure switched off (manual override). The indicator for the position can be
seen by removing the conduit.
Neutral position
Fig. 4 Neutral position
– Indicator is visible and end face lines up with the end of the pipe (mid-posi-
tion).
– Piston can move freely.
– Drive can be driven pneumatically.
Indicator inward
Fig. 5 Indicator inward
– Double-acting drive: turning the handwheel anti-clockwise moves the indicat-
or inward. The valve opens.
– Single-acting drive: turning the handwheel clockwise moves the indicator
inward. The valve closes.
Indicator outward
Fig. 6 Indicator outward
– Double-acting drive: turning the handwheel clockwise moves the indicator
outward. The valve closes.
– Single-acting drive: turning the handwheel anti-clockwise moves the indicator
outward. The valve opens.

7 Assembly
7.1 Assembly without adapter plate
Fig. 7 Assembly without adapter bridge
1. Place the semi-rotary drive on the control shaft of the process valve. The
square of the process valve must sit in the coupling of the semi-rotary drive
(è Fig.1,aB) without tilting.
2. Mount the semi-rotary drive on the connecting flange of the process valve
using 4 corrosion-resistant screws and retaining rings (material: CI).
